Michael still to this day claims he made MTV what it is. And he is right. He is THE reason MTV is/was (probably more towards was lol) a big force and promo tool in the music industry.
But 25 years, well, it doesnt mean he will go. He didnt go to BET for 25 years of Thriller when Ne-yo performed Lady In My Life. He didnt go to Grammy's when a 25 year celebration for Thriller was even on the TV ad. And they were for his PERSONAL achievements.
He DID go to the WMA in 2006 to celebrate the 25th year of thriller (but der, it was the 24th, someone at WMA cant count)... and he was even prepared to sing there (but they shut of his music halfway, idiots)
IF he went, I would do it like this....
Wrap up the T25 Promotions with Michael opening the show with a spectacular tribute to what MADE MTV.. Billie Jean, Beat It and Thriller... A medley, much like the one when he opened these same awards in 1995. Then, like in 1995 with You Are Not Alone, end the performance with a NEW song! Michael opening the 1995 show with "OLD HITS" didnt hurt his performance at all, because he STILL performed his "NEW HIT" as well... So IF he had a new song out by then, he could do the best of both worlds. Thrill people with the old stuff, and hit them with the new one too
